IMPROVEMENT IN CULTIVATORS.

Speeicatiou forming part of Letters Patent No. 118,884, dated July 25, 1865.

To all whom it may concern: l

Be it known that l, \V. D. AMENT, of Muscatine, in the county ot' Muscatine and State ot' Iowa, have invented a new and Improved Cultivator.; and l do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a side sectional View of my invention, taken in the line a; fr, Fig. 2; Fig. 2, a transverse vertical section ot' the same, taken in the line y y, Fig. l.

Similar letters ot' reference indicate like parts.

rlhis invention relates to an improvement in that class of cultivators which are commonly termed ridingscultivators; and it consists in a novel construction ot' certain parts, whereby several advantages are obtained, which will be hereinafter set forth.

A represents the frame of the cult-ivator,

which is of rectangular form, and mounted on two wheels, B I3.

C C represent the plow-beams, the rear parts, a, of which have about a horizontal position, and the front parts, Z), an inclined position, as shown clearly in Fig. 1. The parts b are secured to the parts a by two ratchet-plates, cc, bent so as to form elbows, and secured one to the upper and the other to the lower surfaces of the parts a b at their junction, as shown clearly in Fig. l. The upper ends of the inclined parts b are secured to the front part of the frame A by staple or universal joints d, and the rear ends ofthe parts a have chains e attached to them, which pass over pulleys j' at the rear side ofthe axle D and are connected to treadles E E, the front ends of which are secured by joints g to the upper ends of the front plow-standards, h. By means of these treadles the plows are raised out ot' the ground when required.

The part act' each plow-beam has an upright bar, F, secured to it, said bars passing up through slots in plates G Gr on the frame A, and connected at their upper ends by a crossbar, H, which is fitted loosely on tenons at the upper ends of the bars FF, and secured thereto by pivots t'. The upright bars F F are perforated with a series ot' holes, through which rodsj pass, and these rods are fitted in metal bearings I, which are attached to plates G G. These plates Gr Gr are attached to the frame A by bolts 7c, which pass through slots l in the plates in the frame A, and admit of said plates being adjusted laterally7 in order to vary the width between the plows as may be desired.

By having the plow-beams C G constructed of two parts connected together and to the frame A, as shown, the plow-beams may be moved laterally and kept. parallel with each other, causing a true and equal movement ot' all the plows, and the plow-beams are subjected to a direct draft irom the equalizer or draft attachment. By having the rods or bearingsj titted in metal bearingsl theploW-beams are made to swing with a steady and true motion.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent- The adjustable metallic plate Gr, formed or cast in one piece with the bearings I, substantially as described.
